OFAC - Organic Fertilizer Association of California

Who We Are

The purpose of the Organic Fertilizer Association of California (OFAC) is to:

  • Promote organic fertilizer use and organic cultural practices through education and research
  • Engage in legislative and regulatory activities
  • Communicate issues to its membership and interested parties
  • Facilitate industry communications and activism
  • Formulate industry standards for quality, safety and NOP compliance

This is accomplished by working with various organizations and government agencies, such as the fertilizer and organic programs of the California Department of Food and Agriculture (CDFA) and the United States Department of Agriculture—National Organic Food Program (NOP), which impact the industry.  


Newsletters are distributed to OFAC members and interested parties to keep them up-to-date on issues. 

OFAC provides information and holds seminars on organic fertilizer use and cultural practices.


Regular meetings of the association are scheduled to facilitate communications among industry members, organic certifiers and our customers. 

OFAC helps make growers and the public aware of the important role organic fertilizers play in producing organic food and sustaining our environment.
